It’s no secret that NonStopTuning has offered popular lightweight pulley options for the 86 chassis. Since 2005, NST has offered more options for the Toyota family of engines found in the AE86, including the 16V/20V variations of the 4AGE and 4AGZE, than all other companies combined.

Carrying that tradition forward, NST also offers a lightweight kit for the second coming of the 86 chassis and the FA20 powered Scion FRS, Subaru BRZ, and Toyota 86.

The NST Lite series is a designation used for pulleys that are light-weight versions of their OEMcounterparts. All NST pulleys are built using High quality 6061-T6 aircraft aluminum and are easily 70% to 75% lighter than steel or cast iron OEM pulleys. Every NST pulley is hard anodized for exceptional durability and is a great item for use at the track or on the street.

The NSTCR-Lite Pulley is compatible with naturally aspirated, turbocharged, or supercharged applications, and is compatible with the OEM belt. No belt change is required when this crank pulley is used.

We had the opportunity to test a set of NST pulleys on a stock BRZ. Scott’s world rally blue pearl BRZ came to us as an otherwise unmolested test car. No previously installed performance mods of any kind would ensure that we would get the best raw data possible. The NST Pulley Kit is the only power adder that was added to this car during the session, and all dyno runs were performed on the same dyno, on the same day, at Carboy Racing in southwest Houston.

Peak Horsepower Up by 5 WHP

Torque and response is noticeably improved across the entire power band

HP & TQ gains in the low, mid, and high range of the power band

Conclusion? NST Pulleys improve power, torque, and response across the entire power band. If you look at the area under the power and torque curves you will notice positive gains in the low, mid, and high range when NST Pulleys are used. No other modification in the same price range can offer similar gains across the entire power band. This fact make the NST Pulleys one of the best bang per buck modifications for the FA20 engine.​
